There was quite a surge of people looking for opening times over the bank holiday, as you might well expect. Unfortunately Opening Times doesn't deal well with this at the moment. I've done a few experiments and should be working on this shortly. The plan is to override any standard opening times for a given day. I considered have a bank holiday standard opening time, and just displaying that when appropriate, but I know that even big chain stores vary their openings quite often so I thought it best to enter them each time.
On the technical side on Saturday I rebuilt the server with Ubuntu Hardy Heron and this time compiled Nginx from source. I also switched to use Thin as the ruby web server. Apologies for any downtime suffered during this upgrade, hopefully this should keep things smooth for a while now.
I went to Hack Day last year and it was good fun and I met loads of very clever and interesting people. I've signed up for Mashed this year. I don't know anyone else who is going, so get in touch in you have a great idea I can work on when I get there.
